Definitions
- the invention relates to a vacuum drain system, comprising at least one liquid collector conduit with sections alternatingly ascending and descending in the direction of flow, with a collecting tank that is under vacuum.
- Vacuum conduits for liquids, such as waste water, with alternatingly ascending and descending conduit sections are known and described, for example, in U.S. Pat. No. 3,239,849, German Pat. No. 1,238,858, and German OS. No. 2,455,551, herein incorporated by reference.
- the or each collector conduit is connected to one or more plumbing drains or waste water drains such as a drain from a sink, water closet, bathtub, industrial effluent, etc.
- the water in the conduit collects as it drips in a descending section and forms water plugs that are driven further through the conduit when a plumbing drain connection is opened, because of the sucked-in air.
- the succeeding conduit sections In known systems, the succeeding conduit sections, independently of their incline, have substantially the same cross section whose size is calculated from the quantity of water to be transported.
- the effort was made to have the flow cross section as large as possible, but on the other hand, certain upper limits had to be respected in order to cause the air admitted in bursts into the conduit system, to thrust the water adhead of it and not simply pass through it.
- the problem to which the invention is addressed is to create a vacuum drain system of the described type that functions more efficiently than known systems do.
- This problem is solved according to the invention in that at least one of the ascending conduit sections presents a substantially smaller cross section than that of an adjacent descending section.
- the drawing shows, in a simplified way, one vacuum collector line, with ascending and descending conduit sections, leading to the system's vacuum facility.
- the collector line of the drain system has been assigned numeral 10 as its overall designation. Through it, waste water from a plurality of plumbing drain connections is sucked to a collecting tank 12 of a vacuum facility 14 whose suction pump 16 maintains a specific reduced pressure in tank 12. From time to time the waste water collected in tank 12 is pumped off by another pump 18.
- collecting conduit 10 comprises descending conduit sections 20a, b, c and ascending sections 22a, b, c.
- the descending sections each are inclined downwardly, in the direction of flow to tank 12, such that liquid flowing therein flows downwardly.
- the ascending sections each are inclined upwardly, in the direction of flow to tank 12, such that liquid flowing therethrough flows upwardly.
- Conduit sections 20a, b, c depending upon design capacity, respectively, have an internal diameter of about 110 to 300 mm, whereas the ascending sections 22a, b, c, are made with a diameter of about 50 to 100 mm.
- the ratio of the cross section of a descending section to that of an ascending section is thus in the range of 6:1 to 1.1 to 1.
- the different cross section of the ascending and descending conduit sections is correlated to the differing tendency in the two sections, on the part of air that is admitted into the system in bursts, to pass through the water.
- the advantage of the better entrainment of the water in the ascending section outweighs the disadvantage of greater pipe friction because the ascending sections with narrower cross section are comparatively short with respect to the length of the entire conduit.
- pocket-like depressions 24 can be made at the downstream ends of the descending conduit sections at the junction between the descending and the ascending conduit sections, as shown in the drawing, for example, between sections 20b and 22b.
- the narrower sections are also not joined coaxially to the other sections, but rather are joined in an off center manner with the narrower ascending section connected to the lower portion of the larger cross section of an adjacent descending section.
- the angle between the descending and the ascending sections depends upon local conditions, and may range between 3° and 90°.
